Maybe this is a very basic question but,
In laravel if i use this route:

Route::get('/{campo}','ItemController@show');

and then i try to use this route

Route::get('/mondo/','ItemController@mondo');

I get simply redirect to a ItemController@show with parameter 'mondo' but I can't reach ItemController@mondo because he take mondo like a parameter. How can I let laravel know when i want he take a variable from url and when i don't?
